Jiu-jitsu traces back so far in time we can’t find it’s origines…
We can go as far as 5 thousands years ago when Kalaripayat was practiced by a cast of warrior monks. That was something particular. That is the roots of jiu-jitsu and almost all martial arts when the monk Damo who became later known as Boddidharma traveled north to China 1500 years ago. He meditated for ten years in a cave next to a monastry that would be the most famous place in the world for martial arts : the shaolin monastry. The monks all learned from Boddidharma, who brought buddhism as well into China. His teaching was not only about combat but also meditation and consciousness. That last teaching, or Sutra was called the Laṅkāvatāra Sūtra that is explained in detail here.
That is the core, not only to understand jiu-jitsu but ourself. That is the spirit of jiu-jitsu.
Despite its name jiu-jitsu also contains a “do”
Then as you practice in an academy this take form and melt into the practice. The particularity of brazilian jiu-jitsu is that this void, this spirit, this spriritual core that becomes your eternal and higher strength is accessible to anyone who desire to learn or be initiated. Before martial arts schools used to be hemetic. Jiu-jitsu can be a media, a form through which the spirit, the teaching, the principles are flowing from one to another. The spirit of a martial art is not about bowing to a wall or to someone. It is about realising the importance of consciousness.
That is what came out of experience, learning, practice, travel, human interactions… However you don’t need years to understand. The sensei, the teacher, the instructor can be seen as a transmitor experiencing and sharing an awakening process that pulls you forward…
You open then to your nature, your infinate expansion through consciousness.
